Are the differences between three groups actually meaningful, or could they just be due to random variation? That's what ANOVA helps you find out. 📊 Here's the intuition: 🔹 Between-group variation: Measures how far each group mean is from the overall mean. 🔹 Within-group variation: Measures how much observations...

Elon Musk: If you are creating a company or joining a company the most important thing is to attract great people "If you are creating a company or joining a company the most important thing is to attract great people, so either be with or join a group that's amazing that you really respect, or if you have building a company you have to gather great people I mean all the company is a group of people that have gathered together to create a product or service and so depending upon how talented and hardworking that group is, and the degree to which they're focused, cohesively, and in a good direction, that will determine the success of the company Do everything you can to gather great people, if you are creating a company"

This is how we streamline AI implementation across 26 companies in a PE portfolio. Each company has 10 departments, and each department has 10 workflows. If you do them one at a time, you need "50,000 forward deployed engineers across three years." Our method is to group the companies by system of record. For finance, the 5 companies on NetSuite are one group. The 4 companies on Dynamics are a different group. Then you find what NetSuite can do and what it cannot do. You build only for the gaps. In one group, the processes are still different. The 5 NetSuite companies used 12, 9, 15, 18 and 13 steps for their finance process. The target is 6 steps, with agents at specific points. You will not often make all 5 exactly equal. You can come close if you map each process with the stakeholders before you change it. A single company or 26, sort the work by its system before you build.

This is a masterpiece in explaining just how horrifically warped and subverted the words "all men are created equal" became. They do not mean what you think they meant. They do not mean what you were taught they meant. All of it was a lie told by modern leftists. John Doyle

Garry Nolan says there are more groups doing what skywatcher is doing right now “we know how to call them” “Skywatcher is one group of several that I'm aware of that are doing it independently.” Source -Sol Foundation 🔗 in comments Garry -“The, the information's out there, we, you know, it's already pretty well understood. I mean, look, there's been enough whistleblower types where the information of how to do this has leaked out. You know, we know how to call them. Whether you believe in psionics or not, it seems to be part of the process. So we know how to call them. The question is not can you video them? Skywatcher has already shown that you can video them and there'll be more of that kind of stuff, I think coming in the future, you know, so Skywatcher is one group of several that I'm aware of that are doing it independently. So that's citizen science. I mean, I think the answer is you don't wait for the government to do it, for you. Don't wait for daddy or mommy to tell you what's going on. You just do it yourself. Because as long as you're not going out there with, with guns or energy, weapons, trying to pull something down and, you know, get yourself in a bad situation, there's no reason people can't do it themselves and organize. So, you know, that's, that I think is the threat in a way that one needs to use against the governmental authorities who think that they hold all the, all the, all the marbles at this point, they don't anymore because the people who've been in the program, like Jake and others who've, you know, made that statement publicly, have basically made their knowledge and ability public. So do it.”

"So there's literally a thousand variations of just .30-06 (rounds). I mean, really, when you get to the different powder loads, the different projectile types, all of those things, there's so much variation, and for us to pretend that all through that variation, the spectrum of (target) results are going to be the same, I mean, it's preposterous... ...They're (hollow point bullets) not designed to fragment, they're designed to basically open up so it deforms that projectile much faster. Now, there also are also frangible rounds—frangible projectiles that are designed to fragment. But even with soft point and some of these other more conventional rounds, they do fragment when they hit bone—I mean, that's just a fact." -Gary Melton Paramount Tactical - Gary Melton

The best question to ask a communist that will melt their brains is this: if workers own the means of production, that means all markets are essentially abolished. Everything is given communally. But what if there’s a group of workers at a flag factory and they all decide to make Nazi flags and ban black people from working there, how could you enforce consequences if there’s no market system (there factory can’t fail) nor government? Watch them implode.

Joe Rogan EXPOSES how Big Pharma rigs drug studies. Run 10 studies, bury the 8 that fail, and this is how you get “100% effective” from data that shows the opposite. “You could do 10 studies and 8 of them show this is complete bullshit, but one or two of them show just some sort of statistically significant improvement in something because you've kind of manipulated all the different controls in the study.” “If it's peer-reviewed, the scientists do not get to look at the actual data.” “They get to look at the pharmaceutical drug companies' scientists' version of what the study was.” “So like no one ever gets to see the actual study. So, that's one of the reasons that they can say crazy things like it's 100% effective.” “So, if you have… one person in the vaccine group or the medication group and that person dies and then you have a control group where two people die.” “Well, 100% more died in the control group where they didn't get the medication.” “So that means it's 100% effective.” Joe Rogan

➡️ Quantitative Finance From Scratch, Part 22: Hypothesis Testing. You start with the null hypothesis: the strategy's true average return is zero, so there is no edge. Then you ask how often pure luck would produce a result at least as extreme as yours if that were true. The t statistic divides the average return by its standard error (the typical size of the random error in an average). The p value is the probability of a t statistic at least this far from zero when there is really no edge. At the 95% confidence level, a result counts as significant when the p value is below 5%, and that matches a 95% confidence interval that does not include zero. In this video we simulate a strategy with a small real edge built in (a true Sharpe ratio of 1, daily swings of 1%) for five years. It reaches a t statistic of 1.50 and a two-sided p value of 13.3%. The 95% interval for the average daily return goes from -0.013% to +0.096%, so it includes zero and the result is not significant at the 5% level, even though the edge is real. By chance, the run only showed a Sharpe ratio of 0.67 instead of 1, and five years of data were not enough this time. A useful rule: the t statistic is about the yearly Sharpe ratio times the square root of the number of years. With a Sharpe ratio of 1, you need about four years to reach a t statistic of 2. The biggest trap is testing many rules. Test 100 strategies with no edge at all, and about 5 will still pass at the 5% level by luck. In our run, 7 did. A p value is not the probability that your strategy works. The test assumes independent returns and a market that stays the same, and a real edge can still be too small to survive trading costs. All numbers come from one simulated run with assumed numbers (seed 22). No real market data, no strategy recommendation. Education only, not financial advice. #quantitativefinance #quant #hypothesistesting #trading #statistics

Former NBA star Gilbert Arenas says women should be ashamed if they aren't contributing financially or making their man’s life easier “The idea of this is what attracts you to get what I want, it's just prostitution in a sense. But at some point, I don't want you. You're not an equal. You're just a taker. You're not making my life easier. You're making it harder” “If you are a stay at home wife or girlfriend, then you need to understand what that means. When I come home, is the house clean and the suitcase packed? Are the clothes clean and folded? Do your part to make the entity's life easier. That is the point” “If you're not going to put into making money with me, helping me make money, working with me, or working for me. If I have an assistant, as a woman you should be ashamed of yourself. If your NBA husband, your CEO husband, whatever the fuck he is, has an assistant and that's not your fucking job, nah” “Women, if this what you say when someone says, ‘Hey, what do you bring?’ and you say, ‘I bring the table,’ get the fuck out. I have a table, all the fucking chairs, I have the food. Now what do you bring?” “There are eight billion people in the world. As a woman, I don't need you to say, ‘I can't afford that.’ If you can't afford it, find a dude who wants to pay all your bills. I'm looking for someone who wants to be equal because equal means I'm going to treat you equal” “If I'm paying all your bills, you really have no value to me and I'm going to keep fucking whoever I want to fuck. You have no rules over me. Now, if we’re 50-50 you are valued, which means I'm not going to jeopardize this for that”

A Sharpe ratio is a t-statistic. The null hypothesis: you have no skill: Rich Falk-Wallace (Rich Falk-Wallace, ex-Citadel PM, founder of Arcana) explains: "You can think about a Sharpe ratio fundamentally as a t-statistic against the null hypothesis that you don't have skill. That's not a new framing to a quant. But to a fundamental person — The Sharpe ratio is mostly an attribute of how high quality the product is to the end investor. But it's also a statement of how certain we are that we're generating returns materially different from zero."
